m AWZMA A TTORNEYS Patented Dec. 17, 1929 UNITED ST TES PATENT orrics JAMES H. CLARK, OF DETROIT, MICHIGAN, ASSIGNOR TO BRIGGS MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN REMOTE-CONTROL-LEVER ASSEMBLY FOR DOOR LATCHES Application filed January 3, 1927. Serial No. 158,752.

This invention relates generally to remote control lever assemblies for door latches such as that shown and described in co-pending application Serial No. 123,535 and consists of certain novel features of construction, com binations and arrangements of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is an outside elevation of an assembly embodying my invention.

Figure 2 is a vertical sectional view taken on the line-22 of Figure 1.

Figure 3 is an inside elevation of the construction shown in Figure 1.

' Figure 4 is an outside elevation of a slightly modified form of construction.

, Figure 5 is a vertical sectional View taken on the line 55 of Figure 4.

Referring now to the drawings; 1 is a lock board constituting an inner panel of a door, and 2 is a lever of an assembly embodying my invention. As shown, this lock board 1 is provided with an arcuate-shaped slot 3 and is provided along the lower curved edge and at the ends of said slot with inturned flanges 4 and 5 respectively. Preferably the flange 4 at the lower edge of the slot curves upwardly in spaced relation to the inner face of the lock board and serves as a shield for the lever 2 and a stiffening and reinforcing member for the lock board. The flanges 5 at the ends of the slot preferably project at substantially right angles to the lock board and serve as abutments or stops for the lever. As shown this lever 2 has a substantially flat attaching portion 6 and an offset longitudinally curved portion 7. Preferably the attaching portion is disposed upon the inner side of and is pivotally connected to the lock board 1 at a point above and concentric with the arcuate slot 3, while the curved portion 7 is spaced from and is movable freely over the outer side of the lock board. In the present instance the upper end of the attaching portion 6 is offset slightly inwardly and is secured to a suitable actuating link 8 for the latch bolt at one edge of the door, while the lower end of the attaching portion 6 is offset slightly inwardly and connects into the inner end of the curved portion 7. Preferably this curved portion 7 extends through the arcuate slot 3 and is provided at its lower end with an outwardly projecting lateral portion 9 to which a suit-' able operating handle 10 is cured.

To provide a neat appearance a panel 11 of fabric trimming material is secured upon preferably sethe outer face of the lock boardand has an arcuate slot 12 therein registering with the slot 3, while mounted upon the outer face of this trimming material is an escutcheon 13 that is also provided with an arcuate slot 14 in registration with the slots 12 and 3;

Preferably this escutcheon 13 is secured at its ends to the lock board 1 by means of screws 15 and is provided along the edges of the slot 14 with inturned flanges 16 that overlap and thereby conceal the edges of the slot 12 in the panel 11 of trimming material.

In Figures 4 and 5 I have shown a slight modification in which the lever 20 has a substantially flat attaching portion 21 and a longitudinally curved portion 22. Preferably the attaching portion 21 is disposed upon the inner side of and is pivotally connected to the lock board 1 at a point below and concentric with the arcuate slot 23, while the curved portion 22 constitutes a handle" for the lever and is movable freely over the outer side of the lock board. With this construction the attaching portion 21 is connected at its lower end to the actuating link 8 for the latch bolt and is provided at its upper end with an inwardly offset portion 24:, while the curved portion 22 extends through the slot 23 and connects into the upper end of the offset portion 24.

Thus, from the foregoing description, it

such lever assemblies can be manufactured at a very low cost, are strong and durable, are neat in appearance, and can be readily and separately installed.

lVhile it is believed that from the foregoing description, the nature and advantage of my invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described 7 and that such changes may be resorted to when desired as fall Within the scope of what is claimed.

What I claim as my invention is 1. In an assembly of the class described, the combination with a panel having an arcuate slot therein, of a lever having an intermediate transversely extending portion extending through the slot and having oppositely extending longitudinal portions disposed upon opposite sides of said panel, one of said longitudinal portions being bowed outwardly with respect to said panel and spaced therefrom, and the other of said longitudinal portions being pivotally connected to said panel and having means for receiving a remote control link attaching means.

2. In an assembly of the class described,

the combination with a panel having an arcuate slot therein, of a lever having a portion extending through the slot and having other portions upon opposite sides of said panel, one of said last mentioned portions being substantially fiatand being connected directly to the panel, the other of said last mentioned portions being bowed outwardly with respect to said panel and spaced therefrom.

3. In combination, a lever having an attaching portion and alongitudinally curved portion, and a support for saidlever having a slot receiving a portion of said lever and having flanges at certain edges of said slot constituting a shield and stops for said lever.

4. In combination, a lever having an attaching portion, and a longitudinally curved vportion offset with respect to said attaching.

portion, and a support for said lever having a slot receiving a portion of said lever, a pivot for the lever carried by the support and engaging said attaching portion intermediate the ends thereof, said attaching portion being provided at its free end bcyondthe pivot with means for receiving a remote control link attaching means, a panel of trimming material upon the'outer side of said support and having an arcuate slot registering with the slot aforesaid, and an esoutcheon on the outer side of said panel of'trimming material having an arcuate slot registering with the slots aforesaid and having inturned flanges at the edges of said slot overlapping and concealing the edges of the slot in said panel of trimming material.

5. In combination, a lever having an attaching portion and a portion offset wit-h respect to said attachin portion, a support for said'leverhaving a slot receiving aiportion of the lever, the attaching portion of said lever being pivotally connected to the sup port and having a portion provided with means for receiving a remote control link attaching means, a panel of trimming material upon the outer side of saidsupport and having a slot registering with the slot aforesaid, and an escutcheon on the outer side of said panel of trimming material having a slot registering with the slots aforesaidandhaving inturned portions at'theedges of said slot overlappingand concealing the edges of the slot in said panel of trimming material.

6. In combination, a lever having an attaching portion and a portion offset with respect to said attaching portion and an intermediate connecting portion, a support for said lever disposed between said attaching and offset portions and having a slot receiving the intermediate connecting iportion vof the lever, the attaching portion of saidlev-er I being pivotallyconnected to the support and provided with means for receiving a remote control link attaching means, a panel of triinming material upon one sideof said support between said support and the offsetportion of said lever andihaving a slotlregistering with the slotaforesaid and receiving theconnecting portion of said lever, and an escutcheon on one side of said panelo'f trimming material between said panel and the ofiiset portion of said lever andhavinga slotregistering with the slots aforesaid and receiving the connecting portion aforesaid of :said lever, and fianges atthe edges ofthe-slot in' said escutcheon extending into'the slot insaid panel of trimming material and overlapping and concealing the edges ofthe slot insaid panel of trimmingvmaterial.

In testimony whereof I afli-x my-signature.
